DESCRIPTION
The DAC6574 is a low-power, quad channel, 10-bit
buffered voltage output DAC. Its on-chip precision
output amplifier allows rail-to-rail output swing to be
achieved. The DAC6574 utilizes an I2C compatible
two wire serial interface supporting high-speed
interface mode with address support of up to four
DAC6574s for a total of 16 channels on the bus.
The DAC6574 uses VDD and GND to set the output
range of the DAC. The DAC6574 incorporates a
power-on-reset circuit that ensures that the DAC
output powers up at zero volts and remains there until
a valid write takes place to the device. The DAC6574
contains a per-channel power-down feature, ac-
cessed via the internal control register, that reduces
the current consumption of the device to 200 nA at 5
V.
The low power consumption of this part in normal
operation makes it ideally suited to portable battery
operated equipment. The power consumption is less
than 3mW at VDD = 5 V reducing to 1 µW in
power-down mode.
TI offers a variety of data converters with I2C
interface. See DACx57x family of 16/12/10/8 bit,
single and quad channel DACs. Also see ADS7823
and ADS1100, 12-bit octal channel and 16-bit single
channel ADCs.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
